The serial number is typically engraved on the caseback. On vintage Heuer pieces (pre-1985), it may also appear between the lugs or on the case band. Note: TAG Heuer changed their serial numbering system in 1985 — results above 100,000,000 indicate post-1985 production.
TAG Heuer / Heuer Serial Numbers by Year
The serial number system changed significantly in 1985 when TAG acquired Heuer. Pre-1985 serials are typically 6-digit numbers; post-1985 use an alphanumeric system on many models.

160+ Years of Precision Timekeeping
Edouard Heuer founded Uhrenmanufaktur Heuer-Leonidas in 1860 in Saint-Imier, Switzerland — the same canton as Longines and Breitling. From the beginning, the company focused on precision timing instruments: pocket chronographs, stopwatches, and eventually wristwatches for motorsport timing.
The vintage Heuer era (1963–1985) produced three of the most collectible chronographs of the 20th century: the Carrera (1963, named after the Carrera Panamericana race), the Monaco (1969, the world's first automatic waterproof square-cased chronograph, famously worn by Steve McQueen in Le Mans), and the Autavia (1962, a portmanteau of Automobile and Aviation). These three references have become blue-chip vintage collector pieces with prices that would have seemed impossible when they were simply professional motorsport chronographs.
The 1985 TAG acquisition brought additional resources and expanded the brand's commercial reach. Today, TAG Heuer occupies the accessible luxury chronograph market with the Carrera, Monaco, Aquaracer, and Formula 1 collections, while maintaining the historical heritage that defines the brand's identity.
